Her shocking pictures told the truth about mafia murders – and earned her death threats. Ahead of a powerful film about her extraordinary life, we meet the woman who dared to confront killers. Warning: contains graphic imagery

Letizia Battaglia can still remember the first corpse she photographed: a man lying beneath an olive tree in a field in rural Sicily. It remains a viscerally unsettling image, made all the more so by its telling details: the dead man’s shoeless left foot, the resigned gaze of the policeman guarding the body, the olive leaves hanging low over the spreadeagled torso. The fact that he was a mafioso murdered in a local feud is, insists Battaglia, neither here nor there. “Everyone,” she says quietly, “is equal in death.”

What has stayed with her, over 40 years later, is the smell that hung in the summer air that day and was carried on the breeze. “It was very hot and he had been dead for a few days,” she says, drawing deeply on a cigarette. “Now, as soon as you ask about this photograph, it comes back to me. I can almost feel it, this atmosphere of death.”
